Odd PS3 issue

[#1]

Well it seems everytime i switch my PS3 it screws my OHs wireless connection.
This makes it nigh on impossible for me to play online whilst she is up..
Any ideas as to what might be causing it? It happens when using the either wired or wireless connection or no connection at all.
Very puzzling...

Change the wireless channel that the PS3 is running on

ok i know what the problem is, the wireless controllers are interfering, using the usb cable it all is ok.
but i thought bluetooth and 802.11 worked on different frequencies?

An interesting article on minimizing bluetooth interference shows that it can be difficult getting the two systems to coexist.
